BACKGROUND OF THE INVENTION 1. Field of the Invention

The present invention relates to systems and methods for providing video enhancement for sporting events. More particularly, the present invention relates to systems and methods for providing performance comparison in auto racing broadcasting.

2. Description of the Prior Art

Auto racing (also known as car racing, motor racing, or automobile racing) is a sport involving the racing of automobiles for competition. Some popular auto racing competitions are, for example, NASCAR, INDYCAR, FORMULA ONE, GRAND-AM, and NHRA. These auto racing competitions draw a lot of fans every season. Besides viewing an auto racing event at the track, live television broadcasting provides a convenient way for fans and viewers to enjoy the excitement of the auto racing events. NASCAR is second to the National Football League among professional sports franchises in terms of television viewers and fans in the United States. Internationally, NASCAR races are broadcast on television in over 150 countries. TV broadcasting has improved with the development of camera technologies and computer processing. However, there is little video enhancement and statistical data available during TV broadcasting or subsequent to the broadcast for analytics.

Exemplary US Patent Documents relevant to the prior art include:

DETAILED DESCRIPTION

The present invention relates to video enhancement for sporting event presentation. The present invention provides systems and methods for video enhancement for sporting event presentation. In one embodiment, the sporting event is auto racing.

Auto racing events involves racing of automobiles for competitions. For example, some of the popular auto racing events include NASCAR, INDYCAR, FORMULA ONE, GRAND-AM, and NHRA. Unlike football, basketball, and baseball, TV broadcasting for auto racing events provides little video enhancement and little data available on screen related to the performance of drivers/vehicles. Thus, viewers of auto racing events have a limited viewing experience. Accordingly, there exists a long felt and unmet need for enhancing video presentation for auto racing events and accessing more consumable data to improve broadcast presentation, viewing experience, fan engagement, after event analytics, training, etc.

The present invention provides a server platform for video enhancement for auto racing events. In one embodiment, the server platform is cloud-based. The server platform collects and analyzes real-time raw data from drivers/vehicles in a current auto racing event, thereby creating analyzed data. The server platform is operable to access historical raw data and analyzed data from a previous auto racing event. In one embodiment, the raw data includes data collected from monitoring, probing, sensing, and/or tracking a driver/vehicle in an auto racing event. The raw data further includes video image data from cameras capturing the auto racing event. The server platform is further operable to compare performances of drivers/vehicles based on the raw data and analyzed data from the current auto racing event and historical auto racing events. The server platform is further operable to process video images of the current auto racing event based on the comparison. In one embodiment, the current auto racing event is a live auto racing event. In another embodiment, the current auto racing event is a finished auto racing event of interest.

The present invention provides systems and methods of video enhancement for auto racing broadcast. A server platform is in network communication with at least one input capture device in a current auto racing event and at least one user device. The at least one input capture device is operable to collect and transmit real-time input data relating to the current auto racing event to the server platform. The server platform analyzes the real-time input data, thereby creating analyzed data. The server platform is operable to access historical data for previous auto racing events. The server platform compares driver performances in the current auto racing event and previous auto racing events based on analyzed data and historical data. The server platform overlays a graphical element representing a driver and vehicle for comparison on video images of a driver and vehicle of interest in the current auto racing event. The at least one user device is operable to display the graphical element on the video images of the driver and vehicle of interest via an interactive graphical user interface (GUI). The driver and vehicle for comparison is a ghost driver and vehicle depicted in faded color.

In one embodiment, the systems and methods of the present invention apply not only to auto racing event but also any other competitive event. A server platform is in network communication with at least one input capture device in current event and at least one user device. The at least one input capture device collects and transmits real-time input data relating to the current event to the server platform. The server platform analyzes the real-time input data, thereby creating analyzed data. The server platform is operable to access historical data for previous events stored in a database. The server platform compares element performances in the current event and previous events based on analyzed data and historical data. The server platform overlays a graphical element representing an element for comparison on video images of an element of interest in the current event. The at least one user device displays the graphical element on the video images of the driver and vehicle of interest via an interactive graphical user interface (GUI).

The server platform provides at least one graphical user interface (GUI) to display the processed video images of the current auto racing event. In one embodiment, the at least one GUI is customized for broadcasters, fans, trainers, and other parties who are interested in an auto racing event.

In one embodiment, the GUI is further operable to display statistical data for the comparison of the drivers/vehicles. For example, statistical data of a driver/vehicle in a NASCAR event includes but not limited to a rank of the driver/vehicle, a time off, a speed, a percentage of throttle, a percentage of brake, a steering angle, RPM (revolutions per minute), a lap fraction, time for recent laps, etc.

In one embodiment, raw data, analyzed data, statistical data, video data, and other data related to an auto racing event are stamped with a time code indicating when the data is captured and/or processed. In one embodiment, all the data are synchronized and stored along a timeline in a file format in a database accessible by the sever platform of the present invention. In one embodiment, the file format is annotatable. In one embodiment, the file format is applicable to all kinds of sports.

In one embodiment, the comparison of drivers/vehicles is between different drivers/vehicles in the same auto racing event. In another embodiment, the comparison is between a driver/vehicle in the current auto racing event and a driver/vehicle in a historical auto racing event. In another embodiment, the comparison is for the same driver/vehicle in the current auto racing event and in a historical auto racing event. In yet another embodiment, the comparison is for the same driver between different laps in the current auto racing event.

In one embodiment, for comparison between a current auto racing event and a historical auto racing event, the data and video images of a driver/vehicle in the historical auto racing event is synchronized or aligned with those of the current auto racing event from the beginning of the events. For example, in a live NASCAR event, a historical NASCAR event which took place on the same track is synchronized or aligned to the live NASCAR event from the starting line. In another embodiment, for comparison between different drivers/vehicles in the same auto racing event, the data for all drivers/vehicles are already synchronized along a timeline from the beginning of the same auto racing event. In yet another embodiment, for comparison of the same driver/vehicle at different laps, the data at different laps are synchronized at the starting line of each lap.

In one embodiment, a driver/vehicle is selected from a current NASCAR event or a historical NASCAR event via a GUI to compare with a driver/vehicle of interest in the current NASCAR event. The server platform is operable to overlay/insert an image of the selected driver/vehicle as a ghost driver/vehicle along with the driver/vehicle of interest in the video images of the current NASCAR event. The ghost driver/vehicle is preferably displayed in a faded/washed color. Alternative methods of differentiating the ghost driver/vehicle from the driver/vehicle of interest such as arrows, outlines, different colors, etc. are also within the scope of the present invention.

Statistical data for the ghost driver/vehicle and the driver/vehicle of interest are compared and displayed on the video images of the current NASCAR event along with the image of the ghost driver/vehicle via the GUI. In one embodiment, the ghost driver/vehicle represents a different driver/vehicle in the current NASCAR event. In one embodiment, the ghost driver/vehicle is the same driver/vehicle in a different lap in the current NASCAR event. In another embodiment, the ghost driver/vehicle is a different driver in a historical NASCAR event. In yet another embodiment, the ghost driver/vehicle is the same driver/vehicle in a historical NASCAR event.

In one embodiment, the GUI in the present invention is customized for broadcasters, trainers, fans, and other parties of a specific sporting event. For example, a GUI for a NASCAR event is operable to display video images of the NASCAR event with enhancement information for broadcasting, training and other purposes. A race status is displayed and represented by different flags used in a NASCAR event (e.g., green flag, yellow flag, red flag, black flag, blue flag with diagonal yellow stripe, white flag, and checkered flag used in NASCAR events). For example, a green flag means a NASCAR event has started or resumed. There are different modes for displaying the NASCAR event, including free mode, chase mode, and broadcast mode. In free mode, a bird's eye view of the NASCAR event is displayed. In chase mode, a front, middle, or back view of a vehicle is selected to be displayed. In broadcast mode, a camera view is selected to broadcast. An authorized user is enabled to select drivers/vehicles via the GUI for drivers/vehicles of interest and drivers/vehicles for comparison. Statistical data for selected drivers/vehicles are displayed on the GUI. The GUI is operable to display driving lines of the selected drivers/vehicles. Laps traveled and time spent by a driver/vehicle are displayed via the GUI. In one embodiment, a lap number is displayed as an integer, and the progress of a driver/vehicle of interest for the lap number is represented by the position of an indicator on a lap slider. The position of an indicator on a race slider indicates the total amount of time that has passed in the race out of the total time for the course record, the total time of the race for the ghost driver/vehicle, the total time of the race projected for the race based on the current lap time or the average lap time, and combinations thereof

Referring now to the drawings in general, the illustrations are for the purpose of describing a preferred embodiment of the present invention and are not intended to limit the present invention thereto.

FIGS. 1-11 are screenshots for the GUI displaying a NASCAR event with video enhancement features according to one embodiment of the present invention.

FIG. 1 displays a comparison of two drivers/vehicles in a NASCAR event at lap 22 and a live view of the two drivers/vehicles in broadcast mode according to one embodiment of the present invention. No. 42 K. Larson is selected as a driver/vehicle of interest, and No. 2 B. Keselowski is selected as a ghost driver/vehicle for comparison. The main window displays a comparison of the driver/vehicle of interest and the ghost driver/vehicle. A live window at the top right corner displays the two drivers/vehicles in the NASCAR event in broadcast mode. Advantageously, the present invention provides for comparing a driver/vehicle of interest with a ghost driver/vehicle from a variety of sources, including the ghost driver/vehicle compared to the driver/vehicle of interest on the current lap only (i.e., the ghost driver/vehicle and driver/vehicle of interest are displayed as if they started the current lap at the same time), the driver/vehicle of interest compared to a prior lap of the ghost driver/vehicle in the current race, historically, etc., and any other comparison of interest. Notably, statistics are operable to be displayed for the comparison of the ghost driver/vehicle and the driver/vehicle of interest. The lap fraction statistic indicates the lap number and a decimal portion of how much of the lap the driver/vehicle of interest and the ghost driver/vehicle have completed.
